"When I heard it, I have to say in the past I would have been shocked," the Hall of Fame Giants linebacker said. "But I'm not shocked anymore."
Carson, early in his career back in the 1980s, said he contemplated suicide while driving over the Tappan Zee Bridge. Then he thought about leaving his infant daughter without a father.
"I knew years ago that there would come a point in time where, whether it was transitioning to the game, or there would be guys having these neurological issues, that players were going to be committing suicide," Carson said.
He added, "I said that years ago. Whether it's Dave Duerson, whether it's Andre Waters, whether it's Ray Easterling from two weeks ago, there are guys who are committing suicide."
Carson continued, "So people who look at me, they wonder about me, because I've been so out there in regard to the whole trauma brain-injury thing. I'm fine."
He said he predicted a rash of NFL suicides because of the neurological damage that can occur from playing the game.
"I knew how I felt as a player, having those thoughts of suicide, and you're going through something, and it's like you can't really explain what you're dealing with, and it's neurological," he said.
"You have these deep bouts of depression, and people think you're depressed because you're not playing anymore. You're depressed because you're having neurological issues that are very difficult to describe."
